Rember is a front-end GUI to the 'memtest' command line memory testing program. This application will allow the user to select the number of test loops, as well as the amount of memory to test. There is a 'Log' tab that will allow the user to monitor memory testing. The user can toggle a 'verbose' switch to limit the amount of output, and can also choose to quit Finder and other applications.

Defective memory can cause computers to malfunction, crash, and behave in a variety of ways which can sometimes baffle end users and computer technicians alike. Apple provides hardware test CDs with most of their products, and there are some third-party utilties for Mac OS X which perform memory testing. In my experience, these tools have not always been able to quickly and efficiently diagnose memory problems. Rember has been designed to simplify the testing, and diagnosis of these problems.
